To LZZ whom it may concern.-

Be it known that I, JACOB S. DETRIOK, a citizen of the United States,residing in Baltimore, State of Maryland, have invented 5 certain newand useful uImprovements in Brackets, of which the following is aspecification. f

This invention relates to swinging shelves or brackets especiallydesigned for supportro ing a telephone receiver and transmitter, but

also useful for holding other objects in various positions, such aselectric lights.

One of the objects of the invention is to provide a telephone-holderthat will normally 15 remain in a substantially vertical position aboveorin a line with the upright support and elevated above the place of useof the telephone and which parts will occu y comparatively small spaceand which wil automatic- 2o ally return to the upright elevated positionwhen released after using.

A further object ofthe invention is to provide in such a device means ofadjustment whereby the normal upright position of the 2 5 telephone maybe adjusted vertically, so

that it may be supported and used at differ'- ent elevations.

A further object of the invention is to provide a form of suspendedbracket arranged to 3o`carry a pair of telephones or other objects.

My invention further comprises the novel Y features of construction andoperation, as

hereinafter set forth, and poi'nted out in the claims.

In the accompanying drawings, illustrating one embodiment of myinvention, Figure l'is a front elevation of the device in the normalupright position. Fig. 2 is a vertical axial section showing in brokenlines one ad- 40 justed position of the upright memberr and also showingin broken lines the arm and bracket swung down to position for use. Fig.3' shows detached the clamping device for the adjustable rod. Fig. 4shows the Fig. 5 shows the forked extension of the swinging arm. Fig. 6shows a form of double bracket,

.and Figs. 7 and 8 show details of the latter device.

5o Any suitable form of base, as 12, may be ed from the upper end of thepost 13 is an` 5 5 arm 14, arranged to swing in a vertical plane` 'mentwith the post 13.

downward from a position in substantial alinement with the post 13. Atthe upper end of the arm 14 is pivoted a bracket mem- 'ber comprising anupright member, preferably a tu e 15, having secured at its lower end ashelf member. The latter member is shown as comprising a lateral piece16, on which is pivoted a supporting-plate 17, to

`which latter a telephone-pedestal may be attached in any suitablemanner, as by bent pieces 171. The plate 17 is shown as pivoted byjournal-piece 18 and normally retained in the position shown by means ofa spring 19 fast on the arm 16, holding the plate in contact with a lug20 on the arm. The telephone resting on this plate can be rockeddownward to the position indicated in broken lines in Fig. 2 against thetension of this spring and will return to its normal position relativeto the upright when released.

One form of means of pivotally connectin the swinging arm 14 with theupright member is to provide a forked member 21, secured at the lowerend of the arm. A bolt22, passing through apertures 23 in the fork,serves as pivoting means by which the arm is mounted on the upperportion of the upright member. Suitable means are attached or connectedwith the lower extremities of the fork 21 whereby to normally andyieldingly retain the arm 14 elevated substantially in aline- One ormore springs may be used for this purpose, and in the present instancesprinvs 24 connect screws 36 on the extremities of the fork with thelower portion of the upright member. When the -arm is rocked by pullingthe telephone-bracket downward, these springs will be distended, `asshown in Fig. 2, bracket the s rings will retract the arm to its formeruprig t position and retain it at such place. The fork 21 is shown ashaving across- .piece v211, that will normally be held in co-n tact withthe upright supporting member by the springs, thereby limiting theSwingin of the fork and arm by the springs. It wil be observed fromFigs. 2 and 5 that theforked arms make a slight angle with the arm 14,so that when the springs draw the fork down with the cross-piece inengagement with the upright supporting member the arm 14 will besubstantially vertical.

Suitable means may be provided whereby Y the place of attachment o thefork 21 with the upright supporting member may be ad- 11o and uponreleasing the justed vertically, and in the present embodiment of theinvention the vupright member comprises, essentially, two parts, theupright post 13 and a tubular member 25, slidable on this post. Theupper end of the tube is 'shown as having a head 26, through which thesaid bolt 22 of the fork 21 is passed, thereby pivoting the arm 14 tothe upper part of the tube 25.

For supporting the tube 25 that slides on the post 13 in variousvertical positions in the present instance there is provided a clampcomprising a split ring 27, having a screw 28, extending outward in halfportions from each end of the ring. A wing-nut 29 has a threaded borearranged to engage the two-part screw 28, and the latter is madetapering, so that the nut will cause the parts of the screw, andconsequently the ends of the ring, to approach as the nut is advanced onthe screw. This ring is of an internal diameter to embrace the lowerportion of the post 13 and when the screw is turned toward the ring willserve to bind the clamp on the post and support the tube 25.

The springs 24 in the resent instance are shown as connected wit thetube 25, that carries the arm and fork by means of a clampring 30,having apertured arms 31, into which are tapered screws 32, to whichscrews the lower ends of the springs are attached. The ring 30 isprovided with an extension 33, containing a slot 34, extending inwardfrom the bore of the ring. A transverse bore is made in this extensionand adapted to receive a screw 35, that serves to draw the oppositeportions of the extension together and reduces the diameter of the borein the ring, thereby tightly clamping the ring on the tube 25. Movingthe ring up or down will serve to adjust the tension on the springs 24.

In Fig. 6 is shown a form of bracket provided with two shelves forsupportinol two telephones or other desired objects. ,in the structureshown the upright 15, that is hinged to the arm 14, has secured at itslower end a cross bar or tube 40. On each end portion of the bar isprovided a shelf artending in the opposite direction and normallysupporting the late 41 in its horizontal position. A coilspring 46surrounds the cross-piece 40 at each end portion and has one end securedtothe pivot-piece 42 of the plate 41, while the opposite end of eachspring is secured in the T-piece connecting theupright 15 with thecross-piece 47; This spring is arranged to normally cause the shelf tobear against the arm 45 and retain it in its horizontal position, asshown, and will return it toA such position after being rocked, 'asindicated in broken lines in Fig. 8, the arm 44 serving to limit theswinging of the plate from its horizontal position. VThe base of thetelephones 48 may be secured to the plates 41 by suitable bent pieces49.` y t If desired, the u right 15 can be removed and an electric lightattached to the lupper end of the arm 14, the wires running up throughthe tubes 13 and 14, The arm 14 can be swung to any convenient positionand there retained by tightening the clamp-bolt 22 at the pivot-joint ofthe arm 14.
